The effect of working memory load on selective attention to emotional faces for social anxiety individuals.

Research has confirmed that individuals with social anxiety (SA) show an attentional bias towards threat-related stimuli. However, the extent to which this attentional bias depends on top-down cognitive control processes remains controversial. The present study investigated the effect of working memory (WM) load on selective attention to emotional faces in both high social anxiety (HSA) and low social anxiety (LSA) groups by manipulating WM load through the inclusion of forward counting in multiples of two (low load) or backward counting in multiples of seven (high load) within a modified flanker task. In the flanker task, emotional faces (angry, happy, or neutral faces) were used as targets and distractors. A total of 70 participants (34 HSA participants; 36 LSA participants) completed the flanker task in the laboratory. The results showed that the HSA individuals performed worse when responding to angry targets. Relative to LSA individuals, HSA individuals showed interference from angry distractors in the flanker task, resulting in significantly lower accuracy in identifying angry targets compared to happy targets. These results were unaffected by the manipulation of WM load. The findings imply HSA individuals have impaired attentional control, and that their threat-related attentional bias relies more on the bottom-up automatic attentional process.

Incongruent gestures slow the processing of facial expressions in university students with social anxiety.

In recent years, an increasing number of studies have examined the mechanisms underlying nonverbal emotional information processing in people with high social anxiety (HSA). However, most of these studies have focused on the processing of facial expressions, and there has been scarce research on gesture or even face-gesture combined processing in HSA individuals. The present study explored the processing characteristics and mechanism of the interaction between gestures and facial expressions in people with HSA and low social anxiety (LSA). The present study recruited university students as participants and used the Liebowitz Social Anxiety Scale scores to distinguish the HSA and LSA groups. We used a 2 (group: HSA and LSA) × 2 (emotion valence: positive, negative) × 2 (task: face, gesture) multifactor mixed design, and videos of a single face or gesture and combined face-gesture cues were used as stimuli. We found that (1) there is a distinction in the processing of faces and gestures, with individuals recognizing gestures faster than faces; (2) there is an attentional enhancement in the processing of gestures, particularly for negative gestures; and (3) when the emotional valence of faces and gestures align, it facilitates the recognition of both. However, incongruent gestures have a stronger impact on the processing of facial expressions compared to facial expressions themselves, suggesting that the processing of facial emotions is more influenced by environmental cues provided by gestures. These findings indicated that gestures played an important role in emotional processing, and facial emotional processing was more dependent on the environmental cues derived from gestures, which helps to clarify the reasons for biases in the interpretation of emotional information in people with HSA.

EFFECTS OF SOCIAL INCLUSIONARY STATUS ON SELF-EVALUATION DEPENDS ON SOCIAL ANXIETY

Social inclusionary status might have diverse effects on self-perception. We conducted an online experiment (N=170) to examine the effects of social inclusionary status and social anxiety on self-evaluation. Our hypothesis was that the social exclusion experience will negatively affect self-evaluations in the competence dimension and social anxiety is expected to moderate this relationship. Participants filled out the Liebowitz Social Anxiety Scale and wrote a short autobiographical essay about an experience from their lives when they felt excluded/rejected (exclusion condition) or included (inclusion condition). Self-evaluation was approached with the two dimensions -warmth and competence- as proposed in the Stereotype Content Model. Results had shown that participants’ warmth judgments about themselves were not affected by neither inclusionary status nor social anxiety. On the other hand, inclusionary status had an effect on self-competence evaluations as a function of participants’ social anxiety levels. Accordingly, remembering an inclusive experience (from their past) was related with higher self-competence only among low social anxiety participants. The positive effect of remembering social inclusion experience was not observed among high social anxiety individuals. In conclusion, the effect of social inclusionary status on self-competence assessments was moderated by social anxiety.

Negative and positive self-beliefs in social anxiety: The strength of believing mediates the affective response.

Current cognitive models of social anxiety disorder (SAD) propose that individual, situation-specific self-beliefs are central to SAD. However, the role of differences in the degree to which individuals with social anxiety are convinced of self-beliefs, in particular positive ones, is still not fully understood. We compared how much high and low socially anxious individuals agree with their own negative and positive self-beliefs. Furthermore, we investigated whether agreeing with one's self-belief can explain the relation between negative affect in response to self-beliefs and social anxiety. Specifically, we were interested whether social anxiety increases negative affect in response to self-beliefs through an increase in agreement. We developed a new experimental self-belief task containing positive and negative semi-idiosyncratic, situation specific self-beliefs typical of high social anxiety and included a direct measure of agreement with these beliefs. Using extreme group sampling, we a-priori selected high (n = 51) and low (n = 50) socially anxious individuals. By multi-level mediation analysis, we analyzed agreement with self-beliefs in both groups and its association with affect. High and low socially anxious individuals chose similar self-beliefs. However, high socially anxious individuals (HSA) agreed more with negative self-beliefs and less with positive self-beliefs compared to low socially anxious individuals (LSA). HSA individuals reported increased negative affect after both, exposition to negative and positive self-beliefs compared to LSA. We found that social anxiety increases affective responses towards negative-self beliefs through an increase in agreeing with these self-beliefs. These findings suggest that cognitive models of social anxiety can be improved by including not only the content of a self-belief but also the strength of such a belief. In addition, they emphasize the relevance of positive self-beliefs in social anxiety, which has frequently been overlooked.

Social anxiety inhibits needs repair following exclusion in both relational and non-relational reward contexts: The mediating role of positive affect

The pain of social exclusion can motivate people to capitalize on opportunities to reconnect with others and repair their self-esteem and feelings of belongingness. This effect is often diminished for those with high social anxiety (HSA). Prior research suggests this may be due to their diminished capacity for recognizing and emotionally responding to relational reward cues. We investigated whether non-relational success experiences in the aftermath of exclusion may be an alternative means of repairing threatened self-esteem and belongingness in HSA individuals. In a preregistered, online study, we threatened belongingness and self-esteem in 422 participants by excluding them in a Cyberball game and then assigned them to one of three conditions: Relational Repair, Non-Relational Repair, or a No-Repair control condition. Results showed that both repair contexts facilitated needs repair relative to the no-repair control condition, and mediation analyses suggested this effect was driven by increased positive affect (PA). HSA individuals were less likely to restore needs regardless of condition and this effect appeared to be driven by low PA. Findings emphasize the critical role of PA for restoring threatened needs in the aftermath of exclusion and suggest that HSA inhibits needs repair processes across both relational and non-relational reward contexts.

Peer pressure: Conformity outweighs reciprocity in social anxiety.

Social anxiety (SA) is characterized by a persistent fear of negative evaluation and marked difficulties in forming social relationships. Concerned with falling short of standards, the socially anxious make important efforts to obtain approval within their group. In the current research, we extended previous findings on excessive conformity in social anxiety, by quantifying the indirect effect of social anxiety-related conformity on unrelated third parties. Two hundred and eleven participants were assigned to one of 6 subgroups based on SA cutoffs and experimental condition. Participants first interacted in a Survival task together with 5 other participants (group of reference), and then completed a monetary Prisoner’s Dilemma session against an unrelated and cooperative Person B. Prior to being asked to split the allocated $10, participants were presented with their reference group’s proposed split of the money and also with Person B’s proposed amount to each member of the group. Depending on experimental condition, group members were made to appear either as fair or highly unfair, while Person B was always fair. Participants were thus given two alternatives: reciprocate fairness or conform to unfairness. Our results show that high SA individuals tend to align to the group’s unfair behavior, even though conformity, in this case, is to mistreat an otherwise well-intentioned stranger. Intriguingly, while the general population follows the norms of reciprocity, for the high SA participants, conformity to the group behavior outweighs prosocial reciprocity. Taken together, our findings show that individuals high in SA are more compliant to the group’s demands.

The recognition of dynamic-emotional faces in individuals with high and low social anxiety: An ERP study

Individuals with high social anxiety (HSA) show abnormal processing of emotional faces, which may increase their social anxiety. A growing number of event-related potential (ERP) studies have explored the neural mechanisms underlying the static-emotional face processing of HSA individuals. In view of the ecological validity of dynamic faces, this study will further explore the time course of dynamic-emotional face processing in individuals with HSA. To this end, 30 high and 30 low social anxiety (LSA) participants were asked to perform an identification task of dynamic-emotional faces while their brain responses were recorded using an ERP technique. The behavioral results showed the recognition accuracy of dynamic faces was higher than static faces when these faces were happy. For the P100 component, HSA participants showed higher P100 mean amplitudes of dynamic than static faces in the left hemisphere when they viewed happy, but not angry faces. In addition, increased N170 mean amplitudes of dynamic-happy faces were showed. Furthermore, the LPP mean amplitudes of dynamic faces were smaller than those of static faces. In sum, this study could provide a better understanding of the time course of dynamic-emotional face processing in HSA individuals.

The moderating effects of reported pre-pandemic social anxiety, symptom impairment, and current stressors on mental health and affiliative adjustment during the first wave of the COVID-19 pandemic

ABSTRACT Background and objectives Individuals with social anxiety (SA) have well-established fears of being negatively evaluated and exposing self-perceived flaws to others. However, the unique impacts of pre-existing SA on well-being and interpersonal outcomes within the stressful context of the pandemic are currently unknown. Design In a study that took place in May 2020, we surveyed 488 North American community participants online. Methods We used multiple linear regression to analyze whether retrospective reports of pre-pandemic SA symptoms predicted current coronavirus anxiety, loneliness, fears of negative evaluation, use of preventive measures, and affiliative outcomes, and whether pre-pandemic functional impairment and recent COVID-related stressors moderated these relations. Results Results highlighted the negative effects of pre-pandemic SA on current mental health functioning, especially for participants with higher pre-pandemic functional impairment and greater exposure to COVID-related stressors. Although participants with higher pre-pandemic SA reported currently feeling lonelier and more fearful of negative evaluation, they also endorsed greater efforts to affiliate with others. Conclusions High SA individuals may have heightened desire for social support within the isolating context of the pandemic, in which COVID-related social restrictions enable greater avoidance of social evaluation but may also mask the enduring impairment associated with pre-pandemic SA.

Adults with higher social anxiety show avoidant gaze behaviour in a real-world social setting: A mobile eye tracking study.

Attentional biases are a core characteristic of social anxiety (SA). However, research has yielded conflicting findings and failed to investigate these biases in real, face-to-face social situations. Therefore, this study examined attentional biases in SA by measuring participants’ eye gaze within a novel eye-tracking paradigm during a real-life social situation. Student participants (N = 30) took part in what they thought was a visual search study, when a confederate posing as another participant entered the room. Whilst all participants avoided looking at the confederate, those with higher SA fixated for a shorter duration during their first fixation on him, and executed fewer fixations and saccades overall as well as exhibiting a shorter scanpath. These findings are indicative of additional avoidance in the higher SA participants. In contrast to previous experimental work, we found no evidence of social hypervigilance or hyperscanning in high SA individuals. The results indicate that in unstructured social settings, avoidance rather than vigilance predominates, especially in those with higher SA.

Visual avoidance of faces in socially anxious individuals: The moderating effect of type of social situation

Patients with social anxiety disorder appear to display aberrant gaze behavior across a variety of social situations. In contrast, the gaze behavior of high socially anxious (HSA) individuals from the community seems to depend on the type of situation and the aberration might be limited to gaze avoidance. This study investigated the differential effect of social situation—a face-viewing task and a public speaking task—on gaze behavior in HSA participants from a community sample. Participants’ eye movements were tracked using a wearable eye tracker. Two aspects of gaze behavior were measured: (1) gaze avoidance was assessed by total fixation time, fixation counts, and mean fixation time on faces; (2) hypervigilance was assessed by scan path length and mean distance between fixations. The results confirmed a moderating effect of task on total (though not mean) fixation time on faces and fixation counts. Compared to low socially anxious participants, HSA participants looked less frequently (hence shorter) at the audience during the speech only. This indicates that visual avoidance in HSA individuals does not occur by default, but only when risks of (negative) social consequences are perceived. High and low socially anxious participants showed no difference in hypervigilance in either situation.

ERP evidence for emotional sensitivity in social anxiety

BackgroundEmotional sensitivity involves the ability to recognize and interpret facial expressions. This is very important for interpersonal communication. Previous studies found differences in emotional sensitivity between high social anxiety (HSA) individuals and low social anxiety (LSA) individuals. However, the underlying neural mechanisms are still unclear. The present study explored the effects of expression intensity and social anxiety on emotional sensitivity and their neural mechanisms. MethodsThe HSA group (n = 20) and the LSA group (n = 20) were asked to recognize anger expressions with different intensities in an emotion recognition task. The hit rate, reaction time, early time window (P1, N170), and late time window (LPP) were recorded. ResultsThe results showed that individuals with HSA had a significantly higher hit rate and shorter reaction time than individuals with LSA (p < 0.01). Event-related potential (ERP) results showed that, compared to the LSA group, the HSA group exhibited significantly enhanced N170 and LPP amplitude (p < 0.01). However, the difference in P1 amplitude was not significant (p > 0.05). LimitationsThe participants in this study were a subclinical social anxiety sample, and the effects of other mood disorders were not excluded, partially limiting the generalizability of the results. ConclusionsOur findings suggest that, compared to LSA individuals, HSA individuals are more sensitive to all presented faces. The ERP results indicated that HSA individuals’ high sensitivity to threatening expressions is related to stronger structural encoding and fine processing.

Are avoidance biases in social anxiety due to biases in stimulus coding or in post-coding behavioral tendencies?

On the Approach-Avoidance Task (AAT) high socially anxious (HSA) individuals exhibit increased behavioral avoidance of faces displaying emotional expressions. Two accounts could explain these findings: 1) HSA individuals have a heightened readiness to code faces in terms of emotionality, and all individuals behaviorally avoid faces coded as emotional (pre-behavior coding bias hypothesis), or 2) everyone is equally ready to code faces in terms of emotionality, but when faces are coded as emotional HSA have a heightened tendency to behaviorally avoid such stimuli (post coding behavioral bias hypothesis). To test these hypotheses, we created the Stimulus-Coding AAT. Participants categorized emotional and non-emotional faces in terms of either gender or emotional expression, before making a standard AAT response. Time to make each type of categorization, and to execute AAT responses following categorization, was assessed in 32 HSA and 32 LSA participants. Groups did not differ in their relative speed to categorize face stimuli on the two dimensions. When participants coded faces in terms of their emotionality, HSA relative to LSA participants demonstrated increased behavioral avoidance of emotional faces. We conclude that these findings are inconsistent with the pre-behavior coding bias hypothesis and support the post-coding behavioral bias hypothesis.

Electrophysiological Measures of Visual Working Memory in Social Anxiety.

Socially anxious individuals are very sensitive to threatening information in the environment, so visual working memory (VWM) is of great significance for them. However, the influence of social anxiety on VWM is unclear. In the present study, we aimed to investigate the VWM in individuals with social anxiety using electrophysiological techniques. Event-related potentials (ERPs) of high socially anxious (HSA) individuals and low socially anxious (LSA) individuals were recorded during a change-detection task with two memory conditions (two and four items). Electrophysiological results indicated that compared with the LSA individuals, the HSA individuals had significantly more active contralateral delay activity (CDA) in condition of memorizing four items. However, there was no significant difference between the HSA and LSA groups in response accuracy in the conditions memorizing two and four items. From the electrophysiological results, individuals with high social anxiety could maintain more information in VWM. However, maybe anxiety consumes the available cognitive resources to compensate for the supposed to be impaired effective performance, so that individuals with high social anxiety perform the same as individuals with low social anxiety in terms of behavioral outcomes.

Gaze Behavior in Social Fear Conditioning: An Eye-Tracking Study in Virtual Reality.

The vigilance-avoidance hypothesis of selective attention assumes that socially anxious persons initially direct their attention toward fear-related stimuli and subsequently avoid these social stimuli to reduce emotional distress. New technical developments provide tools to implicit measure overt attention on fear-related stimuli via eye-tracking in ecological valid virtual environments presented via a head-mounted display. We examined in 27 low (LSA) and 26 high socially anxious (HSA) individuals fear ratings, physical behavior (duration of approach), hypervigilance (time to first fixation), and attentional avoidance (count of fixations) toward virtual female and male agents (CS) during social fear conditioning (SFC) and extinction in virtual reality (VR). As hypothesized, generally SFC was successfully induced and extinguished concerning the fear ratings. Our findings partly support the vigilance-avoidance hypothesis as HSA directed especially at the first half of the fear acquisition their initial attention more at CS+ than CS− agents, and avoided subsequently the CS+ more than the CS− agents during the fear acquisition. In contrast, in LSA participants initial and sustained attention did not differ between CS+ and CS− agents during fear acquisition. We conclude that HSA individuals guide their initial attention to emotionally threatening stimuli and subsequently avoid the threatening stimuli to possibly reduce their emotional distress, whereas LSA individuals regulate themselves less in their (fear) responses during SFC. Measuring implicit gaze behavior within a well-controlled virtual environment is an interesting innovative tool to in deeply investigate the impact of attention on emotional learning processes.

Selective gaze direction and interpretation of facial expressions in social anxiety

Fear of negative evaluation is the hallmark of social anxiety. We examined the hypothesis that, to facilitate detection of negative evaluators, an anticipatory coping strategy in social anxiety involves selective early gazing at the eyes of other people. Eye fixations were assessed while participants watched video-clips displaying dynamic facial expressions with prototypical (happy eyes and a smile) or ambiguous (a smile but non-happy eyes) smiling faces. High socially anxious (HSA) undergraduates with clinical levels of anxiety on questionnaire measures and low-anxious controls (LSA) judged expressers' un/trustworthiness (Experiment 1) or un/familiarity (Experiment 2) of expressions. Social anxiety was especially associated with reduced trustworthiness evaluation (interpretative bias) of ambiguous—but not of unambiguous—smiling faces. Further, HSA viewers mistrusted faces with novel, unfamiliar expressions more than LSA viewers did. Thus, the interpretative bias for ambiguous expressions could be due to their being unfamiliar. Importantly, HSA viewers selectively looked earlier at the eye region (attentional bias), whereas LSA viewers preferentially looked at the smiling mouth. Presumably, the early attention to the eyes by HSA individuals enhances detection of expressive incongruences, thus leading to untrustworthiness judgments. These biases are functional, in that they would facilitate recognition of untrustworthy expressers (e.g., with fake smiles).

Intrusive social images in individuals with high and low social anxiety: a multi-method analysis.

Models of social anxiety suggest that intrusive images/memories are common in social anxiety and contribute to the maintenance of social anxiety. We examined the context and phenomenological features of intrusive social images using quantitative and qualitative measures across various levels of social anxiety. Undergraduate students (n = 191) completed measures of social anxiety (i.e. Social Interaction Anxiety Scale and Social Phobia Scale) and wrote a description of an intrusive social image. Individuals who reported an intrusive social image (n = 77) rated the frequency, interference and phenomenological (e.g. vividness, emotional intensity) characteristics of the image. A content analysis of the intrusive image narratives was completed by independent raters. High social anxiety (HSA) increased the likelihood and frequency of experiencing intrusive images, and to some extent the interference caused by these images. However, the characteristics of these images with regard to their content and quality were similar across levels of social anxiety. Among participants who provided narratives, HSA individuals (n = 34) did not differ from low socially anxious (LSA) individuals (n = 28) in themes that reflect concerns about their own thoughts, actions and behaviours. However, HSA individuals reported greater concerns about how other individuals would react, and their intrusive images were often from an observer perspective when compared with LSA individuals. These results are interpreted in relation to cognitive models of emotion, memory and cognitive behavioural models of social anxiety.

Overestimation of threat from neutral faces and voices in social anxiety

Background and objectivesSocial anxiety (SA) is associated with a tendency to interpret social information in a more threatening manner. Most of the research in SA has focused on unimodal exploration (mostly based on facial expressions), thus neglecting the ubiquity of cross-modality. To fill this gap, the present study sought to explore whether SA influences the interpretation of facial and vocal expressions presented separately or jointly. MethodsTwenty-five high socially anxious (HSA) and 29 low socially anxious (LSA) participants completed a forced two-choice emotion identification task consisting of angry and neutral expressions conveyed by faces, voices or combined faces and voices. Participants had to identify the emotion (angry or neutral) of the presented cues as quickly and precisely as possible. ResultsOur results showed that, compared to LSA, HSA individuals show a higher propensity to misattribute anger to neutral expressions independent of cue modality and despite preserved decoding accuracy. We also found a cross-modal facilitation effect at the level of accuracy (i.e., higher accuracy in the bimodal condition compared to unimodal ones). However, such effect was not moderated by SA. LimitationsAlthough the HSA group showed clinical cut-off scores at the Liebowitz Social Anxiety Scale, one limitation is that we did not administer diagnostic interviews. Upcoming studies may want to test whether these results can be generalized to a clinical population. ConclusionsThese findings highlight the usefulness of a cross-modal perspective to probe the specificity of biases in SA.

Neural mechanisms of proactive and reactive cognitive control in social anxiety

Social anxiety—the fear of social embarrassment and negative evaluation by others—ranks among people's worst fears, and it is often thought to impair task performance. We investigated the neurocognitive processes through which trait social anxiety relates to task performance, proposing a model of the joint contributions of reactive control, theoretically associated with conflict monitoring and activity of the dorsal anterior cingulate cortex (dACC), and proactive control, theoretically associated with top-down regulation and activity of the dorsolateral prefrontal cortex (dlPFC). Participants varying in their degree of trait social anxiety completed the Eriksen flanker task while electroencephalography (EEG) was recorded. Task-related left dlPFC activity was indexed by relative left prefrontal EEG (inverse alpha), and conflict-related dACC activity was indexed by the N2r component of the event-related potential. Stronger activity in both regions predicted better response control, and greater social anxiety was associated with worse response control. Furthermore, for all participants, greater left prefrontal EEG activity predicted better behavioral control, but for high social anxiety participants only, greater N2r responses also predicted behavioral control. This pattern suggests that low social anxiety individuals engaged a proactive control process, driven by dlPFC activity, whereas high social anxiety individuals relied additionally on a reactive control process, driven by conflict-related dACC activity. These findings support a model of control that involves different patterns of interplay between proactive and reactive strategies and may help to explain self-regulatory impairments in social anxiety.

Don't stand so close to me: A behavioral and ERP study of preferred interpersonal distance

The space between people, or interpersonal distance, creates and defines the dynamics of social interactions. Given that invasion of one's interpersonal space may trigger threat and anxiety, a critical question is if high vulnerability to social anxiety (SA) is associated with avoidance and attentional biases when anticipating invasion to one's interpersonal space. Therefore, the current study sought to examine the behavioral mechanisms, time course and neural correlates underlying the threat of interpersonal distance invasion with a focus on different SA levels, using both a behavioral and an ERP experiment. Preferred interpersonal distance was assessed using a paradigm that involves responding to different virtual protagonists (friend or stranger) approaching the participant by indicating where one would like the protagonist to stop. In addition, participants' level of social anxiety was measured. The behavioral experiment indicated that levels of SA predicted one's preferred interpersonal distance such that higher SA individuals preferred further distance from a stranger. At the neural level, across groups, early (N1) but not late (LPP) differences were found between stranger and friend conditions. Importantly, SA individuals were characterized by attenuated early ERP responses, suggesting less attentional resources allocated to social stimuli. The results suggest that high SA individuals feel discomfort earlier than others in social engagement, which may lead them to stand further away, thus creating less communicative social interactions.
